The variation is deals will out weigh the variations in those markets unless you plan on buying a huge number of properties.

Of course there can be many variations, but that's the division I make, and read often on the boards here.

Well sometimes it takes some trial and error, and I think every investor needs to understand that has to happen sometimes (rather than expecting perfection all the time).

Some of my most profitable deals long term have been 0.75% deals and some of my least profitable ones have been 2% deals, and much variation in between ... so, to me at best it is a meaningless metric, at worst it is the opposite in that it has in my experience been slightly inverse to the profitability.

A real variation of strategies, ages, experiences etc.

In ALL instances, this agent agrees and in just a few moments, I have now created a good relationship with them ( always the intention ).Going back to the problem, there is no right or wrong answer, only trial and error, as every market is different and every investor has different skill sets and personalities.

Some people are saying online that there is a lot of variation within the neighborhoods.

While there are many variations in markets, my experience has been that removing a bedroom drops the value of a property.

I guess some of this will just be trial and error.

There was also a 12 page addendum where i promise to indemnify and hold harmless seller and his broker and where i waive my rights to pretty much everything including a trial by jury.
